The nurse assessing a premature newborn infant auscultates a continuous machinery-like murmur.
This finding is associated with which congenital heart defect?
Pulmonary stenosis
Patent ductus arteriosus
Ventricular septal defect
Coarctation of the aorta
The Correct Answer is B
This is because a patent ductus arteriosus is a congenital heart defect that involves a defect in which the fetal shunt between the aorta and the pulmonary artery fails to close. This causes a continuous machinery-like murmur that can be heard on auscultation.
Choice A is wrong because pulmonary stenosis is a narrowing of the pulmonary valve or artery that obstructs blood flow to the lungs. It causes a systolic ejection murmur that is best heard at the upper left sternal border.
Choice C is wrong because the ventricular septal defect is a hole in the wall between the ventricles that allows blood to flow from the left to the right side of the heart. It causes a loud, harsh holosystolic murmur that is best heard at the left lower sternal border.
Choice D is wrong because coarctation of the aorta is a narrowing of the aorta that reduces blood flow to the lower body. It causes a systolic murmur that radiates to the back and weak or absent femoral pulses.

Correct Answer is B
Explanation
A way to establish rapport. Doing a simple magic trick using gauze is a way to gain the child’s trust and attention, and to make the dressing change less stressful and more fun. This is appropriate for a 5-year-old child who is in the stage of initiative versus guilt according to Erikson’s theory of psychosocial development.
Choice A is wrong because 5-year-old children are curious and imaginative, and they enjoy magic tricks and fantasy play.
Choice C is wrong because a simple magic trick is not too distracting, but rather a way to engage the child and reduce anxiety.
Choice D is wrong because a simple magic trick is not inappropriate due to the child’s cognitive development. According to Piaget’s theory of cognitive development, 5-year-old children are in the preoperational stage, which means they can use symbols and language to represent objects and events.
A magic trick using gauze is a symbolic representation of something else, which the child can understand and appreciate.
